Description of the male, redescription of the female and new records of Odo patricius Simon, 1900 (Araneae: Zoridae)

摘要

The family Zoridae (F.O. Pickard-Cambridge, 1893) is currently represented by 14 genera and 79 species distributed worldwide (Platnick, 2012), of which only the genera Xenoctenus Mello-Leitao, 1938 and Odo Keyserling, 1887 are present in Americas. Xenoctenus is represented by four species, all endemic to Argentina, while Odo has, so far, a total of 27 species distributed in Central America, South America, West Indies and Australia (Platnick, 2012). The type species of Odo is O. lenis Keyserling, 1887, a specimen female described from Nicaragua. The genus Odo has never been revised and given its wide distribution and number of species, it is probably a polyphyletic genus and a complete revision is required. Also, no new material of O. lenis or O. patricius has been described since 1900.As a result of a series of collections by the first author in recent years in the Tarapaca Region of northern Chile, several specimens from one species of the genus Odo were collected. To date, the only species described from Chile is Odo patricius Simon, 1900 and this species was easily identified by illustrations of the type and specimens provided by Dr. Diana Silva. Odo patricius was described by Simon (1900: 53) based on a brief description of shape the female epigynum: "Plaga genitalis ovato transversa, rufula, antice, in medio profunde et obtuse emarginata, utrinque rotunda et foveolata, in medio processu lato, arcuato, leviter canaliculato, apicem versus leviter ampliato et obtuso divisa". There has not been any subsequent reference of this species in Chile.
